摘要： A variable valve timing control apparatus of an internal combustion engine has a drive rotary member rotated by an engine crankshaft, a driven rotary member fixedly connected to a camshaft and transferring a turning force from the drive rotary member to the camshaft, and a phase-change mechanism changing a relative rotational phase between the drive and driven rotary members and having an intermediate rotary member installed between the drive and driven rotary members for a relative rotational phase control. The variable valve timing control apparatus further has a holding mechanism and a releasing mechanism. The holding mechanism forces the intermediate rotary member and holds the relative rotational phase between the drive and driven rotary members, and the releasing mechanism releases a holding state of the holding mechanism.

摘要： A variable valve timing control apparatus of an internal combustion engine includes a phase change mechanism configured to control engine valve timing by changing a relative angular phase between a timing sprocket and a camshaft by braking torque application via an electromagnetic brake. A flow control valve is arranged downstream of an oil supply passage that supplies cooling oil into an inside of the phase change mechanism. The flow control valve includes a valve element configured to control a flow rate of the oil supplied into the inside of the phase change mechanism, by changing an opening area of a valve bore communicating the oil supply passage by way of an advancing/retreating motion of the valve element in the valve bore, and a temperature-sensitive member configured to create the advancing/retreating motion of the valve element responsively to a temperature of the oil.

摘要： In a structure in which an opening-and-closing timing of an intake valve and/or an exhaust valve is varied due to a rotational phase of a camshaft with respect to a crankshaft of an internal combustion engine being varied, the rotational phase is detected at each rotational period of the camshaft on the basis of a reference rotational position of the crankshaft and a reference rotational position of the camshaft which have been detected, and on the other hand, the rotational phase is detected in an arbitrary timing regardless of the rotational period of the camshaft. Further, a correction value for correcting the rotational phase detected in an arbitrary timing is learned with the rotational phase detected at each rotational period of the camshaft as a reference.
